Acu-Rite CNC 3500i user manual Using the Z Work Offset Update Feature, 233

Using the Z Work Offset Update Feature

If you would like to calibrate all your tools to a fixed Z axis location on the machine, and then use the Z Axis Work Offset to shift all the tools to the top of a part, you must use the G141 Edge Finding cycle with Spindle Probing parameter updateTloOrWorkOffsetZAxis set to WorkOffset. Only Q4, Q5, and Q6 cycle parameters will affect the Z-axis.

First, use Q6 to set the spindle probe tool length offset to the fixed surface on the machine where all the tools are calibrated.

Next, use Q4 or Q5 on the top of the work piece or to where you want the Z zero to be located, to set the Z-axis work offset shift to that Z position.

Both, the tool length offset and the G53 work offset must be active before the Z part zero point will be correct. If either one of these is not active at the same time, a collision could occur.
